TOP FOR CANS AND OTHER REGEPTACLES.

Specification of Letters Patent.

Patented Sept. 7, 1915.

Application filed August 1, 1907. Serial N 0. 386,618.

To all whom it may concern:

Be it known that I, FRANK S. HYATT, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Tops for Cans and other Receptacles, of which the following is a specification.

My invention relates to caps or closures for cans, bottles and similar receptacles for toilet powder, tooth-powder and the like in which the cap or closure consists of two parts, each being perforated, one part being adapted to rotate to bring the perforations together to open the receptacle or to close the receptacle as the case may be.

One of the objects of my inventidn is to so construct the superimposed parts of the caps in which the perforations are located so as to stiffen the metal in these parts and thereby always obtain a more close contact between the caps whereby leakage will be obviated and to so arrange the perforations in the caps that the contents of the receptacle can be shaken out on What is called the natural line of discharge.

To the above ends my invention consists in constructing the top of the caps tapered in a manner such that the perforations located in the sides thereof will be adapted to discharge the contents of the receptacle in aline at which the receptacle would naturally be shaken, or substantially at an angle of 45. 7

The invention also consists in the improved construction of can closures and in the manner of their operation hereinafter more particularly described and then specified in the claim.

I am aware that closures for cans have been made in which the tops of the caps provided with perforations have been fiat or very nearly so, also that it is common to have the perforations in the side of the neck. In these constructions however, namely the first named, the receptacle must be inverted to shake out the contents, while in the second case, the receptacle must be first inverted to force the. contents into the neck and then shaken sidewise to discharge, or shaken practically sidewise at all times. Also in these cases where the top of the caps are made flat or nearly so, the metal in the caps being very thin gets out of shape by powder getting between the caps and being squeezed together when the caps are closed after which the caps will not make close contact and the powder will. leak through. I obviate these difiiculties by bulging out the top of the cap into a cone or a hemisphere or the like which stiffens and reinforces the metal which will not then yield to the force of the small amount of powder which may get wedged between the caps. Also by making the perforations in the side of this bulged or cone-shaped cap the powder can be discharged by shaking the receptacle at an angle of approximately 45 which is the natural line at which a receptacle is shaken.

My invention consists also in the details of construction and combination of parts hereinafter more particularly described and then set forth in the claim.

In the accompanying drawings, Figure 1 illustrates in side elevation the preferred form of closure constructed according to my invention. Fig. 2 is a vertical central section through Fig. 1. Fig. 3 is a plan view of my improved closure. Fig. 4 is a side elevation of a modification.

1 indicates the body of a receptacle such as used to hold tooth-powder, toilet-powder or the like and is provided with a cap or closure 2. In the preferred form of carrying out my invention the top 2 of the cap 2 is bulged upward into a cone terminating in a sharp apex as illustrated in Figs. 1 and 2. Mounted to rotate upon the top of the cap 2 is a cap 3, the top portion of which is bulged to coincide with and fit over the top 2. 7 By so constructing the tops of the caps, the metal is greatly stiffened thus preventing the top getting out of shape due to powder which may get in between the two caps.

The top of each cap is provided with an opening or perforations in the side thereof and owing to the angle of thetop, when the perforations are made to coincide by rotating the cap 3, the contents of the receptacle can be readily discharged by shaking the can at an angle Without having to invert it. To effect this condition the sides of the tops are preferably so located that the openings are disposed at an *angle of approximately 45 to the verticaLjA pin or projection 4 formed on or otherwise suitably secured to the sides of the cap 2 and preferably on the vertical wall or neck thereof engages the cap 3 in the slot 5 formed preferably in the vertical wall or neck of the cap 3. The said slot 5 is of irregular line, that is, the slot is straight for a distance equal to the amount ofrotation it is necessary to give the cap 3 to close the perforations. After the perforations are closed and on further rotation of the cap 3 the pin or follower 4 hits an incline or cam 5 of the slot 5 and forces the top of the cap 3 to jam tightly on the top 2 of the cap 2. To open the can the cap 3 is rotated in the opposite direction when the follower 4 first raises the top of the cap 3 just a trifle to take it out'of engagement with the top 2 of the cap 2 after which the cap 3 moves in a horizontal plane until brought to a stop by the follower hitting the end of the slot 5. 7

- A modification in the form taken by the bulged top is illustrated in Fig. 4, in which the sides of the top are shown as curved surfaces tapering toward the apex, the discharge opemngs being located, as before, at an :ilngle of approximately 45 to the vertica I do not limit myself to the particular form of top shown and described, except as specified in the appended claim. Also the slot and follower might be reversed in their location, that is, the slot might be in the neck of the cap 2 and the follower in the cap 3 or two or more slots and their attendant followers or pins might-be provided around the periphery of the caps.

What I claim' as myinvention is:

A closure for cans comprising a fixed and a rotary cap, each of said caps being provided with an opening .or openings adapted to register with each other, the walls of the caps in which the openings are formed being arranged at such an angle to the body of the can that the contents will be discharged by gravity in a substantially vertical direction when the can is held in the natural position for pouring the material.
